OK before I start please do not judge me. Me and my boyfriend have broke up since November; however I was still messing with him. My last period was Dec 17 2009. I had sex on the 30th and 31st The 4th, and the 8th of Jan with him unprotected however I was messing with another man only once and that was on Jan 13th but we used a condom but when he pulled out the condom was still inside there. I have 37 day cycles so my next expected period would have been on Jan 24th. What is the possibilty that it is my boyfriends?
PS. I started experiencing tender breasts around the beginning of jan. and the other symptoms showed up three days after I had sex with the other dude.
